Note: Combustible wall finish materials and/or surround materials must not be allowed to encroach the area defined by the appliance front face (black
sheet metal). Never allow combustible materials to be positioned in front of or overlapping the appliance face (see Figures 65 and 66 on Page 34 ).
Non-combustible materials, such as surrounds and other appliance trim, may be installed on the appliance face with these exceptions: they must not
cover any portion of the removable glass panel or control compartment.
Vertical installation clearances to combustible mantels vary according to the depth of the mantel. See Figure 9. Mantels constructed of non-combustible
materials may be installed at any height above the appliance opening; however, do not allow anything to hang below the fireplace hood.
WARNING
Failure to position the parts in accordance with these
diagrams or failure to use only parts specifically
